Insulated Glass is customized to your specifications and unique requirements. At High Performance Glazing, our Insulated Glass (IG) units allow you to reduce sound, decrease energy loss and seal out moisture.

We offer a wide variety of Insulated Glass units by hermetically sealing two or more panes of glass separated by spacers, also known as A double pane windows, together using our fully automated vertical sealing lines. Look to High Performance Glazing for a variety of options, using tinted glass, silk screened patterns, Low-E and reflective coating, laminated or tempered thermal units and much more. Some of the benefits include reducing heat and energy efficiency for your glass unit.


The customer can create a unique design, depending on their requirements, while achieving desired aesthetics and improving solar control and thermal performance.

With our two automated insulated glass unit production lines and large-capacity glass manufacturing capabilities, HPG can provide consistent lead times, and high-volume manufacturing to meet the most stringent requirements without compromising quality.​
